The 40 story Deutsche Bank did not take the hammer-blow of being struck by 125 tons of airliner traveling at about 300 mph (which, more that likely, popped a few rivets in the girders that hold the building together), and immediately thereafter get anointed with 11,000 gallons of accelerant (burning jet fuel), nicely distributed by pouring itself down elevator shafts and stairwells.

Nor, in the case of Building 7, did it have a 65,000 gallon tank of diesel fuel (which had already been tagged as dangerous) in the basement explode.

Just because one steel building remains standing during a fire doesn't mean that another will.

That straw isn't going to keep you afloat, Froth.
